George Osborne has been accused of behaving like a lout during the Corfu holiday on which he met Russian tycoon Oleg Deripaska at billionaire Nat Rothschild's villa.

Other holidaymakers said a motorboat carrying Osborne and his family swept through a stretch of water that was packed with swimming children.

Angry mum Candida Jones said the Osbornes seemed arrogantly oblivious to those around them as they headed towards a jetty.

She told the Guardian newspaper: "Surely no one would drive a boat through crowded water?

"Couldn't those on board see that there was nowhere to moor as the pier was packed with children playing?

"Several parents, in several languages, complained loudly this was an inappropriate place to bring a motorboat."

Candida, whose three-year-old daughter was playing on the jetty, said once Osborne's boat had moored the family left the nanny to struggle along with the bulk of their luggage. She added: "It wasn't very Greek at all. Indeed it was extremely English in that old imperial way."

Other witnesses said there was "no backward glance, no apology, no hint of embarrassment" from Osborne.
